to a module, dictionary, or a list of modules and/or dicts. See UI modules for more details. • websocket_ping_interval: If set to a number, all websockets will be pinged every n seconds. This can help proxy servers which close idle connections, and it can detect if the websocket has failed without being properly closed. • websocket_ping_timeout: If the ping interval is set, and the server doesn’t receive receive a ‘pong’ in this many seconds, it will close the websocket. The default is three times the ping interval, with a minimum of 30 seconds. Ignored if the ping interval is not set. Authentication and
